IMPROVEMENTJN SASH-FASTENERS.-

Specification forming part of Letters Patent No. 178,292, dated June 6, 1876 application filed April 24, 1876.

To all whom it may concern Be it known that I, ELIAS J. HALE, of Foxcroft, of the county of Piscataquis and State of Maine, have invented a new and useful Improvement in Sash-Fastenings; and do hereby declare the same to be fully described in the following specification and represented .in the accompanying drawings, of which Figure 1 is a sectional elevation, and Fig. 2 a transverse section; ot'a window-frame and its two sashes with myimproved fastening applied thereto. Fig. 3 is a side view of the bolt, and Fig. 4 a perspective view of the bolt-actuator.

In carrying out my invention I use a perforated bolt, applied to a 'window-fram, as described, in combination with an actuatingspring, provided with an arm, and applied to said bolt and frame, as hereinafter more fully described and definitely claimed.

In the drawings, A denotes the windowframe, and B and 0 its sashes, the lower of the said sashes being movable vertically within such frame.

There is inserted in a hole, h, made horizontally in the frame, a slide-bolt, D, both be ing arranged with the lower sash in manner as shown. Such sash has a series of notches or bolt-receivin g holes, a a, made in it, to open out of that vertical edge of it which is next to the bolt.

The bolt has a perforation or hole, b, bored in it at or near its middle, such hole being to receive a stud, c, projecting from and making part of the actuator E, which consists of a wire bent in manner as shown in Fig. 4, the part 01 of it constituting what may be termed the arm, and the part 0 being the spring.

The bolt may be inserted in the sash, and the actuator be applied directly to the latter and the bolt, in which case the frame should have a series of notches or recesses to receive the bolt, in order for the sash to be supported by it at different heights in the frame. It is preferable, however, to have the bolt and the actuator applied directly to the frame, as herein first explained.

By pressing the thumb against the arm of the actuator the said actuator may be moved so as to force back the bolt out of engagement with the sash. On the thumb being removed from the arm the spring of the actuator will cause the bolt to be thrown forward into engagement with the sash when at any proper height to receive the bolt.

I usually construct the bolt of wood; but it may be of metal or other suitable material.

The actuator, being composed of a single piece of'wire, can be made very .cheaply, and is-of easy application to the frame.

I claim-' 1. As an improved article of manufacture, the perforated bolt D, in combination with the single piece of wire E, bent as represented, so as to form a combined spring, 6, arm d, and stud c, and applied to such bolt, as set forth, the two being arranged with the sash and is supporting-frame, essentially as specified.

2. The frame A, provided with the bolt-receiving hole h, the actuator-receiving chamber f, the perforated bolt D, and the wireE, bent as represented, so as to form a combined spring, 6, arm 01, and stud c, all being arranged and applied substantially as set forth.

ELIAS J. HALE.
